Ballarat Technology Park is bracing to lose one of its biggest tenants when the state government GovHub is completed on the Civic Hall site in 2020.

The State Revenue Office shifted 200 jobs from Melbourne to Ballarat in 2001, building a $5 million, purpose-built office space in Mount Helen in the process.

Earlier this week staff were notified of the move, which is set to take place following the completion of the CBD GovHub in 2020.

The SRO currently house 300 of the 1450 employees working at the Mount Helen site.

Tech Park executive director Jeff Pulford said while the State Revenue Office had been a major player at the Mount Helen site over the past 16 years, he was confident the office space would be filled swiftly.

“Obviously they are an important part but they're not the only presence on site and we'll be working hard to fill their space,” Mr Pulford said.

“We’re very confident we'll be able to find another user when they leave, there's nothing specific about the design that would prohibit another organisation taking over.”

Earlier this year the government department signed a three-year extension of its lease, taking it to the expected completion of the Civic Hall site.

While the state government is yet to offer a timeline for when the SRO will shift, in May it was confirmed as one of eight departments which would be represented in the new building.

SRO employees will join workers from departments including Education and Training , Justice and Regulation, Economic Development, Jobs, Transport and Resources, Consumer Affairs Victoria, Environment, Land, Water and Planning, VicRoads and Service Victoria at the new site which will house 1000 public servants.

Given the timing of the completion of the lease SRO employees are likely to be among the first to make the move after the government confirmed entries to the new building would be staggered.

Mr Pulford said the university was keen to maintain its relationship with the office after it left Tech Park in order to assist graduates in finding employment.
